FREDERICK O. HELLMUTH, OF BROOKLYN, NEW YORK, ASSIGNOR TO HIM- SELF AND JOHN MUNZ, JR, OF SAME PLACE.

CARPET-FASTENER.

$BECIFICATION forming part of Letters Patent No. 334,170, dated January 12, 1886.

Serial No. 163,376. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK O. HELL- MUTH, of Brooklyn, county of Kings, and State of New York, have invented certain new 5 and useful Improvements in Carpet-Fasteners,

of which the following is a specification.

This invention has reference to a cheap, simple, and effective fastener for carpets, matting, and other coverings; and it consists of a botro tom plate or washer screwed to the floor and .of a flat top plate having a threaded shank wit-h tapering point, that screws through the carpet or matting and into the threaded opening of the bottom plate, so as to retain thecar- [5 pet or matting in position between the plates.

In the accompanying drawings, Figure 1 represents a top view of a carpet or matting with my improved fastener. Fig. 2 is a top view of the bottom plate of the fastener; Fig.

:0 3, a vertical transverse section of the fastener;

and Figs. 4 and 5 are a top view and a vertical central section of the top plate of the fastener.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the disk-shaped bottom plate of my improved fastener, which plate is permanently attached to the floor by screws a a. The bottom disk, A, is provided with a screw-threaded opening, a, 30 through which passes the threaded shank b of the top plate, B, which shank is pointed at the end, so as to pierce the carpet or matting and enter into the floor. The top plate, B, like the bottom plate, A. is rounded off at the upper edge, the top plate having, furthermore, socket-holes (Z d, for being taken hold and screwed down on the bottom plate, A. The carpet or matting is interposed between the plates A and B. and securely retained by the same.

The bottom plate, A, may'jbecountersunk in the floor, though for most purposes this will not be required.

When fastening rugs to carpets, the bottom plate embeds itself into the carpet, so that it projects but slightly above the same.

By unscrewing and detaching the top plate the carpet, matting, or other covering may be readily taken up for cleaning, it being quickly replaced without requiring tacks or other fastening devices.

Having thus described my invention,I claim as new and desire to secure by Letters Patent A carpet-fastener consisting of a bottom plate having a central threaded opening and r holes for the fastening-screws, and a flat top plate having a threaded shank at the under side and socket-holes in the top of said plate, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

FREDK. O. HELLMUTH.
